Abstract
The present invention relates to a multi-chambered conduit insert which can be utilized to convert a single chambered conduit into a multi-chambered conduit. In particular, the conduit insert includes a plurality of cooperating longitudinally extending walls having curved outer surface portions and defining a plurality of parallel spaced apart coextensive chambers. When the conduit insert is inserted within the single chambered conduit, the curved outer surface portions of at least one of the chambers in the lower half of the insert is in line-to-line contact with the adjacent inner supporting surface of the single chambered duct, thus causing only minimal contact with the interior wall of the existing conduit and enabling the multi-chambered conduit insert to be fed into the existing conduit with the expenditure of minimal energy. In the preferred embodiment of the invention, two identical conduit inserts are disposed in back-to-back relationship and form an insert assembly for insertion into the single chambered conduit.
